Method and assembly of replacing receptacle seal

1. An assembly for replacing a seal of an associated fluid coupling receptacle without removing the receptacle from an associated housing structure, the coupling including a receptacle body having a through bore end a poppet member carrying a seal disposed in the bore, the seal selectively engaging a valve seat in the body for precluding fluid flow through the receptacle body, the assembly comprising:

a poppet depressing member configured for mounting on the body and extending through the bore into selective engagement with the poppet member;

a seal removing member that selectively engages a worn seal through the bore when the poppet member is spaced from the valve seat via the poppet depressing member; and

a seal advancing member for inserting a new seal over the poppet member after removal of the worn seal therefrom.

2. The assembly of claim 1 wherein the poppet depressing member includes at least one pivotal locking member that selectively engages an outer end of the body for securing the poppet depressing member thereto.

3. The assembly of claim 2 wherein the poppet depressing member includes a second pivotal locking member, the first and second pivotal members located adjacent opposite ends of a central portion that spans across the bore of the body.

4. The assembly of claim 3 wherein the poppet depressing member includes a threaded member extending from the central portion that is selectively advanced and retracted through the bore into selective engagement with the poppet member for moving the poppet member relative to the valve seat.

5. The assembly of claim 2 further comprising a restraining member that cooperates with the poppet depressing member and engages the at least one pivotal locking member to retain the poppet depressing member on the body.

6. The assembly of claim 5 wherein the restraining member is an annular collar received over the poppet depressing member.

7. The assembly of claim 1 wherein the seal removing member includes a finger configured for engaging receipt with the seal on the poppet member.

8. The assembly of claim 7 wherein the seal removing member includes first and second members pivotally joined together, the first member dimensioned for receipt through the bore from an open end of the body with the poppet depressing member mounted on the body, and the second member extending at an angle relative to the first member so that leveraged seal extracting forces can be applied thereto for removal of the worn seal.

9. The assembly of claim 1 wherein the seal advancing member includes a sleeve having an elongated recess allowing installation of the seal advancing member into the bore when the poppet depressing member is mounted to the body.

10. A method of replacing a worn seal of a fluid coupling, the coupling including a body having a bore extending inwardly from an open end thereof and a poppet member carrying a seal received in the bore that selectively engages a valve seat, the method comprising the steps of:

moving the poppet member from the valve seat through the open end of the bore;

advancing a tool member for selectively engaging the worn seal through the open end of the bore;

extracting the worn seal from the poppet member;

advancing a new seal through the bore from the open end thereof:

advancing a tool member for inserting the new seal;

installing the new seal on the poppet member; and

allowing the poppet member to freely move relative to the valve seat.

11. The method of claim 10 comprising the further step of allowing the poppet member to engage the valve seat after removal of the worn seal therefrom.

12. The method of claim 10 wherein the worn seal extracting step includes engaging a minor peripheral portion of the worn seal and axially pulling the peripheral portion toward the open end of the bore whereby the remainder of the seal is removed from the poppet member.

13. The method of claim 10 wherein the installing step includes incrementally advancing the new seal through the bore and over the poppet member by step advancing the new seal and poppet member.
